BOTTLE.

SPECIFICATION forrning' part of Letters Patent No. 726,594, dated April28, 1903. Application filed February 10, 1903. Serial No. 142,795. (Nomodel.)

To aZZ whmn it may concern;

Be it known that I, PHILIP O. TRAVER, a citizen of the United States,residing at Far Rockaway, county of Queens, and State of New York,haveinvented certain new and useful Improvementsin Bottles, of which thefollowingis a specification sufficient to enable others skilled in theart to which the invention appertains to make and use the same.

My improvements relate to means for closing bottles and other originalpackages and are designed to render the same practically non-refillablein a commercial sense.

The invention consists in the construction and arrangement of partshereinafter described and claimed specifically,whereby provision is madefor discharging the contents of the bottle or package through openingsthat are closed automatically by back flow or pressure.

In the accompanying drawings, Figures 1.

and 2 represent sectional elevations illustrating the practicalapplication of my invention to the neck of a bottle, respectivelyshowing the latter in vertical and horizontal positions. Fig. 3 is aView similar to Fig. 1, showing a modification in which the auxiliarycheckvalve is omitted. Fig. 4 is a perspective view of the valve-weight.

The neck 7) of an ordinary bottle or package B is provided with anextension E, secured to the neck by any suitable means,as by a metalliccoupling-sleeve O, the lower edge of which is bent over the shoulder 19of the bottle, as shown in Fig. 3, the neck I) being formed either withor without the tightening screwthread 6 (shown in Figs. land 2,) as maybe desired. It will be seen that the upper part of the coupling-sleeve Oengages with and conforms to the externally-conical lower portion e ofthe extension E, thereby holding the extension in place upon the neck bof the bottle B. A packing p is preferably interposed between theabutting ends of the neck I) of r the bottle and its extension E toinsure a liqapproximately to the inclined inner side walls 6 of theextension E, and its sides are preferably formed with grooves 10 to,which facilitate the flow of the liquid out of the bottle. It will benoted by reference to Fig. 3 that the incline of the interior side walls6 is such that even when-the bottle is held horizontally they tend tothrow the weight backward, so that it acts through its link L1 to keepthe valve closed upon its seat 19 until the bottle is inclined with itsmouth downward at an angle of twenty degrees or more. Hence if thebottle has been emptied by pouring out its contents it is obvious thatliquid cannot be made to flow into the bottle While the latter is ineither a vertical or horizontal position, or in any intermediateposition, and if immersed in a liquid at an angle below the horizontalsurface thereof it is obvious that the contained air would prevent theentrance of the liquid.

It is true that the air might be removed by suction, and to provideagainst the latter contingency I provide the interior of the extension Ewith a delicate spring-valve V, which yields readily to admit of theexit of the contents of the bottle, but closes instantly upon the leastback pressure. Thus even though the air should be exhausted from thebottle while, say, the latter is submerged the partial vacuum createdthereby in the bottle would only tend to hold the valve V more firmly onits seat to the exclusion of any external fluid. The auxiliaryspring-valve V is seated upon a partition or diaphragm 6 formed in theneck of the extension, said partition being formed with the holes orperforations Q The stem 1) of the valve V passes through this partition6 and is formed with a shoulder 22, between which and the under side ofthe partition e is interposed a delicate metallic spring 8, which tendsconstantly to hold the valve V down upon the partition e thereby closingthe openings 6 Above the diaphragm e the neck of the extension E isfitted to receive the ordinary cork or stopper K.

In use the bottle is first filled, and then the extension E is appliedand permanently secured to the neck I) of the bottle by the metalliccoupling-sleeve C or other mechanical expedient, after which the cork kmay be removed and the contents withdrawn by tilting the bottle to theproper degree, leaving the bottle practically non-fillable in acommercial sense, as hereinbefore set forth.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A bottle having a neck formed with a valve-seat, and with anextension formed with converging side walls, a valve for engaging saidseat, a conical weight connected With said valve and engaging with saidconverging side walls formed on the interior of the bottle whereby theconical weight tends constantly to thrust the Valve against its seatuntil the bottle is inclined downward below the horizontal,substantially as set forth.

2. The combination of the bottle having a neck formed with an annularvalve-seat an extension of the neck permanently secured thereto andformed with internally-converging side walls,a conical weight restingbetween said converging side walls, a valve engaging with the saidannular valve-seat in the neck, and a rigid link pivotally attached tothe said valve and connecting it with the said conical weight for thepurpose described.

3. The combination of the bottle having a neck formed with an annularvalve-seat, an extension of the neck formed with internallyconvergingside walls, an external metallic coupling-sleeve permanently securingthe extension to the neck, a conical weight resting between saidconverging side walls, a valve engaging with the said annular valve-seatin the neck, and a rigid link pivotally attached to the said valve andconnecting it with said conical weight for the purpose set forth.

4:. The combination of a bottle having a neck formed with an annularvalve-seat, an extension of the neck permanently secured thereto andformed with internally-converging side walls, a conical weight restingbetween said converging side walls, said weight being formed withperipheral grooves for the purpose set forth, a valve engaging with thesaid annular. valve-seat in the neck, and a rigid link pivotallyattached to the said valve and connecting it with said conical weight,substantially as described.

5. The combination of the bottle having a neck formed with an annularvalve-seat, an extension of the neck permanently secured thereto andformed with internally-converging side walls, a conical wedge restingbetween the said converging side walls, a valve engag ing with the saidannular valve-seat in the neck, a rigid link pivotally attached to thesaid valve and connecting it with said conical wedge, and an auxiliaryspring Valve arranged in the said extension for the purpose andsubstantially in the manner set forth.

6. The combination of a bottle having a neck formed with an annularvalve-seat, an extension of the neck permanently secured thereto andformed with internally-converging side walls and with a perforatedpartition above said converging side walls, a springvalve engaging saidperforated partition, a conical weight resting between said convergingside walls, a valve engaging with the said annular valve-seat in theneck and a rigid link pivotally attached to the said valve andconnecting it with the said conical weight, for the purpose described.
